INSULATED RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 762,669, dated June 14,1904.

Application filedNovember 13, 1903- Serial N0. 181,009. (No model.)

T0 at whom it may concern.-

Be it known that we, GEORGE A. I/VEBER and PERCY HOLBROOK, citizens ofthe United States, and residents of the borough of Manhattan, city,county, and State of New York, have invented certain new and usefulImprovements in Insulated Rail-Joints, of which the following is aspecification accompanied by drawings.

This invention relates to improvements in insulated rail-joints, butmore particularly to the construction of insulated twin joints; and itsobjects are to improve upon the construction of such joints and enablethem to be readily assembled and taken apart without disturbing therails.

Further objects of the invention will hereinafter appear; and to theseends the invention consists of an insulated joint for carrying out theabove objects embodying the features of construction,combinations ofelements,and arrangement of parts, having the general mode of operationsubstantially as hereinafter fully described and claimed in thisspecification and shown in the accompanying drawings, in which Figure 1is a transverse sectional view of a joint embodying the invention havingtwo wooden filling-blocks between the rails next to the rail-webs with ametal bar between said blocks. Fig. 2 is a transverse sectional view ofa joint in which metal bars are arranged between the rails next to therail-webs with the wooden filling-blocks between said bars. Figs. 3 and4 are transverse sectional views of a joint in which all threefilling-blocks are of metal. Fig. 5 is a transverse sectional view of ajoint in which all three filling-blocks are of wood. Fig. 6 is a topplan view of ajoint like that shown in Fig. 1, having wooden fillersbetween the rails next to the rail-webs and showing the metal barbetween the wooden blocks broken. Fig. 7 is a top plan view of a jointlike that shown in Figs. 3 and 4 in which all three metal fillers arebroken and do notextend continuously across the joint. Fig. 8 is a topplan View in which all three filling-blocks are made continuous, themiddle one being either metal or wood and the outer ones being metal.

Referring to the drawings, Arepresents the rail-tie, upon which the railends B, O, D, and E rest. Posts F, of insulating material, may beinserted between the meeting faces of the rail ends or else air-gaps maybe left for insulating purposes. The rail ends of each pair B C and D Eare insulated from each other and each rail end is insulated from allthe others, according to the constructions in the drawings and to bedescribed and claimed.

In all of the figures filling-blocks G, preferablyof wood, are arrangedalong the webs of the rails on the outside, while between the railsfilling or separating blocks or bars are inserted to space the railsapart the desired distance and maintain a rigid joint.

As shown in the figures, three filling blocks or bars are arrangedbetween the webs of the rails, the object of this construction being toenable the joint to be taken apart and assembled without disturbing therails. If one continuous solid filling-block were inserted between therails, it could not be removed upwardly without separating the'rails,and this is disadvantageous and not permissible in many instances,because it is found necessary often to alter the joint and replace someof the parts without disturbing the rails. According to thisconstruction after the bolts are removed the filling-blocks between therails may be removed by first taking out the central one and thenremoving the others.

In Fig. 1 the filling-blocks H adjacent the webs'of the rails are shownof Wood, while the central middle bar I is made of metal. The blocks Hand bar I may be continuous and extend across the joint or else they maybe broken. It is preferable to have the wooden blocks H extendcontinuously across the joint, and if the central metal bar I is brokenit is not necessary, of course, to insulate it from the bolts J. If the'bar I is continuous, an insulating-sleeve K, of suitable insulatingmaterial, as fiber, should be arranged beneath the bar I over the bolt.If

the bar I is made discontinuous or-broken, as

in Fig. 6, the insulating-sleeve K may be dispensed with, and preferablythe post L, of insulating material, should be inserted between themeeting faces of the parts of the bar, as shown in Fig. 6.

Preferably outside of the outer wooden filling-blocks G continuous metalbands or straps O are arranged, which are insulated from the bolts inthe usual manner by means of the insulating-sleeves P and washers Q.Metal liners or take-up blocks R are preferably inserted between the barI and the blocks H at each side to take up play. Liners R of differentthicknesses may be inserted as desired to take up play.

In Fig. 2metalfilli11g-blocks S are arranged adjacent the webs of therails,with a wooden filling-block T arranged between said blocks S. Withthis arrangement if the metal blocks S are continuous and extend acrossthe joint they should be insulated from the bolts J and from the rails,as shown by the insulating ma terial U of any suitable character, suchas fiber, and by means of the sleeves K. As be fore, the metal liners ortake-up blocks R are inserted between the filling-blocks. If thefilling-blocks S and T are discontinuous, the insulation U and K (shownin Fig. 2) is not necessary.

In Figs. 3 and i all three filling-blocks are shown of metal, with themetal liners or takeup blocks R inserted between them. If the metalfilling-blocks are continuous, as shown in Fig. 8, and extend across thejoint, insulating material U and the washer K, of insulating material,are needed, as shown in Fig. 4, or else the outer blocks S may beinsulated from the rail-webs by means of the insulatingwashers V. If thefilling-blocks S and T are discontinuous, as shown in Fig. 7, theinsulating material U and sleeves K are not necessary; but insulatingmaterial may be inserted between the meeting faces of the ends of themetal filling-blocks. In Fig. 5 all three filling-blocks are shown ofwood, which makes a very good construction.

Obviously some features of this invention may be used without others,and the invention may be embodied in widely-varying forms.

Therefore, withoutlimiting the invention to the construction shown anddescribed nor enumerating equivalents, we claim, and desire to obtain byLetters Patent, the following:

1. An insulated rail-joint, comprising the meeting ends of pairs ofrails, with a plurality of longitudinally-extending filling blocks orbars arranged sideby side between the rails, and bolts for securing theparts of the joint together, for substantially the purposes set forth.

2. An insulated rail-joint, comprising the meeting ends of pairs ofrails, means at the outside of the joint for maintaining the rails inalinement, blocks arranged along the railwebs between the rails, with aseparating-bar between said blocks, and bolts for securing the parts ofthe joint together, for substantially the purposes set forth.

3. An insulated rail-joint, comprising the meeting ends of pairs ofrails, with a plurality of longitudinally-extending filling blocks orbars arranged side by side between the rails, bolts for securing theparts of the joint together, and metal liners or take-up blocks betweensaid filling-blocks, for substantially the purposes set forth.

h. An insulated rail-joint, comprising the meeting ends of pairs ofrails, means at the outside of the joint for maintaining the rails inalinement, blocks arranged along the railwebs between the rails, with aseparating-bar between said blocks, bolts for securing the parts of thejoint together, and metal liners or take-up blocks between the saidfillingblocks and separating-bar, for substantially the purposes setforth.

In testimony whereof We have signed this specification in the presenceof the subscribing witnesses.
